Storage Unit Size Guide: Which Size Fits Your Clermont Move?

By Sunny Storage Team

Picking a storage unit size is mostly a guessing game — until you know roughly what each size holds. Rent too small and you’re playing Tetris on move-in day; rent too big and you’re paying for empty air. This guide explains the unit sizes at Sunny Storage in Clermont, what typically fits in each, and how to decide between climate-controlled and drive-up.

How storage unit sizes work

Unit sizes are listed as width x depth in feet. A 10x10 unit is 10 feet wide and 10 feet deep, or 100 square feet of floor space. Because you can stack boxes and stand furniture upright, the usable space is really about volume, not just floor area — good packing can let you fit into a smaller unit.

Unit sizes at Sunny Storage

According to our website, unit sizes at Sunny Storage include 5x5, 5x10, 5x15, 7x10, 7x17, 10x10, 10x15, 11x15, 10x20, 10x25 and 10x30, offered as climate-controlled units. The 10x15, 10x20 and 10x30 sizes are also available as drive-up units. Availability changes, so check the current unit list on sunnystorage.com.

The “what fits” guidance below is a general rule of thumb, not a guarantee — how much you can fit depends on your furniture and how you pack.

Small units: 5x5, 5x10 and 5x15

5x5 (25 sq ft)

About the size of a small closet. Typically good for:

• A dozen or so boxes
• Seasonal decorations, small furniture like a nightstand or chair
• Business files or document boxes
• College dorm overflow

5x10 (50 sq ft)

About the size of a walk-in closet. Typically good for:

• The contents of a small bedroom or studio-apartment overflow
• A twin or full mattress, a dresser and boxes
• Sports gear, bikes and tools

5x15 (75 sq ft)

A long, narrow unit. Typically good for:

• A bedroom set plus boxes
• Long items like rugs, kayaks or lumber laid along the depth

Mid-size units: 7x10, 7x17, 10x10 and 10x15

7x10 (70 sq ft)

A bit wider than a 5x10, which makes it easier to place furniture side by side. Often a fit for a one-bedroom’s worth of furniture with few boxes.

7x17 (119 sq ft)

Roughly comparable in floor area to a 10x10 or a little larger, in a deeper format. Useful for longer pieces like sectional sofas.

10x10 (100 sq ft)

A common middle-of-the-road size. Typically holds:

• The furniture of a one-bedroom apartment
• A queen bed, dresser, sofa, TV and boxes
• Renovation overflow from one or two rooms

10x15 (150 sq ft)

Typically fits a two-bedroom apartment or small home’s furniture and boxes. Also available as drive-up at Sunny Storage, which makes loading heavy furniture easier.

Large units: 11x15, 10x20, 10x25 and 10x30

11x15 (165 sq ft)

A little more room than a 10x15, handy for larger furniture pieces.

10x20 (200 sq ft)

About the size of a one-car garage. Often fits the contents of a two- to three-bedroom home, including appliances. Also available as drive-up.

10x25 (250 sq ft)

Typically fits a three-bedroom home with appliances, or business inventory and equipment.

10x30 (300 sq ft)

Our largest listed size. Often fits a four-bedroom-plus home or substantial business inventory. Also available as drive-up.

Climate-controlled or drive-up?

• Climate-controlled is the better choice for wood furniture, electronics, documents, photos, artwork and clothing — anything sensitive to Florida humidity. (See our guide: Do You Need Climate-Controlled Storage in Clermont, FL?)
• Drive-up lets you park right at your unit’s door, which is ideal for heavy, bulky and durable items you’ll load and unload often.

Five tips to choose the right size

1. List your big items first — beds, sofas, dressers, appliances. These drive the size.
2. Count your boxes (a quick walk-through of each room helps).
3. Plan a walkway if you’ll need to get things out mid-storage.
4. When in doubt, size up slightly if you’ll be adding items over time.
5. Use month-to-month flexibility — Sunny Storage leases are month-to-month, so you can change unit size later as your needs change.
